Action Steps for
Sun Protection
While some exposure to sunlight can be enjoyable, too much can be dangerous.
Overexposure to ultraviolet (UV) radiation from the sun can result in a painful
sunburn. It can also lead to more serious health problems, including skin cancer,
premature aging of the skin, cataracts and other eye damage, and immune system
suppression. Children are particularly at risk. This fact sheet explains simple steps
to protect yourself and your children from overexposure to UV radiation.
Be SunWise
Most people are not aware that skin cancer, while largely preventable, is the most
common form of cancer in the United States. More than one million cases are
reported annually. By following some simple steps, you can still enjoy your time in
the sun and protect yourself from overexposure. The U.S. Environmental
Protection Agency (EPA) recommends these action steps to help you and your
family be “SunWise.”
Do Not Burn
Sunburns significantly increase one’s lifetime risk of developing skin
cancer, especially for children.
Avoid Sun Tanning and Tanning Beds
UV light from tanning beds and the sun causes skin cancer and
wrinkling.
Generously Apply Sunscreen
Generously apply sunscreen: about one ounce to cover all exposed skin
20 minutes before going outside. Sunscreen should have a Sun
Protection Factor (SPF) of at least 15 and provide protection from both
ultraviolet A (UVA) and ultraviolet B (UVB) rays. Reapply every two
hours, even on cloudy days, and after swimming or sweating.
Wear Protective Clothing
Wear protective clothing, such as a long-sleeved shirt, pants, a wide-
brimmed hat, and sunglasses, when possible.

2. Seek Shade
Seek shade when possible and remember that the sun’s UV rays are strongest between
10 a.m. and 4 p.m.
Use Extra Caution Near Water, Snow and Sand
Water, snow and sand reflect the damaging rays of the sun, which can increase your chance
of sunburn.
Check the UV Index
The UV Index provides important information to help you plan your outdoor activities in
ways that prevent sun overexposure. The UV Index forecast is issued daily by the National
Weather Service and EPA. Visit www.epa.gov/sunwise/uvindex.html.
Get Vitamin D Safely
Get Vitamin D safely through a diet that includes vitamin supplements and foods fortified
with Vitamin D. Don’t seek the sun.
Early detection of skin cancer can save your life. A new or changing mole should
be evaluated by a dermatologist.
Special Considerations
for Children
Recent medical research shows that
it is important to protect children
and young adults from overexposure
to UV radiation. For babies under 6
months, the American Academy of
Pediatrics recommends
(1) avoiding sun exposure, and
(2) dressing infants in lightweight
long pants, long-sleeved shirts, and
brimmed hats. Parents can also
apply sunscreen (SPF 15+) to small
areas like the face and back of the
hands if protective clothing and
shade are not available.
EPA’s SunWise Program
In response to the serious public
health threat posed by overexposure
to UV radiation, EPA is working
with schools and communities
across the nation through the
SunWise Program. SunWise is an
environmental and health education
program that teaches children how
to protect themselves from
overexposure to the sun.
The UV Index forecasts the strength of the sun’s harmful rays.
The higher the number, the greater the chance of sun damage.
